Follow Up Warning To Increasing The Alcohol Level In Your Wine

I received a very insightful reponse to my most recent post on increasing the alcohol level in your wine, which I thought I should share with you all as there is a “darker side” to it that you should be aware of!

“I have a couple comments on your blog post.  First of all, you should add a caution statement about adding sugar into fermenting wine.  It needs to be added very slowly.  The first time I did this, I dumped about 4 lbs of sugar into my 6 gallon primary while it was still actively fermenting.  WOW what a mess.  It foamed up like crazy and overflowed the primary bucket and went all over the floor.  Lesson learned. 
 
The next point is that I have found that adding extra sugar at the beginning has much the same affect if all you want is about 15% alcohol.  If you start with a brix of about 30-32 I usually end up with at least 15% alcohol without having to add sugar a second time.
 
Lastly, there may be a consideration on the type of yeast you use.  Some yeasts will burn themselves out and drown in the alcohol when it gets up around 13-14%.  I have not experimented much with this but I do know that Cote des Blancs has a good tolorance for higher alcohol content.
 
As far as the taste is concerned, you may find that the final RS needs to be higher in the bottled wine if the alcohol content is higher to achieve the same taste as you’d have with a lower alcohol content.  That has been my experience anyway.
 
I hope this information helps.

Thanks Mark – certainly worth mentioning to everyone!

How Can I Increase The Alcohol Content?

I received an email the other day asking what kind of sugar was needed to increase the alcohol content of a typical wine to 13 or 14% and I thought this would make a great blog post!

So if you’re interested in learning how you can increase the alcohol content of your wine read on!

What you’ll want to use is corn sugar, which you can buy from your local wine making supply shop.

Incidentally – if you’re into making your own beer you can use it also to carbonate your beer in the bottle (so it has multiple uses).

To increase your alcohol level you typically would do this as part of the primary fermentation and it is called “chaptalization” and is a common practice when making port or other fortified wines to increase the alcohol content.

Basically you let your primary fermentation happen and once the S.G. reduces to the point when you would rack to your secondary you add the sugar to your wine must (in the primary) so that you can reenergize the yeast to produce more alcohol (typically adds another 3 or 4 %).

So in essence you are doing your primary fermentation twice before you transfer your wine must to your secondary.

I followed this procedure when I made a chocolate raspberry port kit from Winexpert and I can tell you it definitely works.

To help you all further I tracked down some online instructions from Winexpert for one of their port kits  and this should point you in the right direction if you wanted to give it a try.

P.S.S. He was also curious if the extra alcohol affected the taste and if so how. Would love to hear your comments on this!
